Default Capacitor naming in notebook schematics

Hi,

I need to replace a 0402 ceramic cap that mysteriously vanished from existence when I was reflowing some ram chips on a Lenovo mainboard.
So, since I have the schematics I thought it would be easy to locate the missing cap and get a new one, but Lenovo has some (for me) unusual naming scheme for their caps. It is labeled as SCD047U6D3V1KX-GP
The schematics even give an example of the naming scheme as seen in the pic,
but I am not sure which value they mean. maybe the D means decimal? so that would be a .047F or 47nF / 6.3V 0402 X5R then?

I do not want to make another stupid mistake

more arbitrary names by lenovo or whoever OEMs...

Looks like you probably got it right, at least assuming things can be extrapolated: SMT ceramic 0.047F10%, 6.3V, 0201 sized most likely, X7R/X5R
